A nurse is collecting data from a client about range-of-motion for various joints. Which of the following should the nurse identify as an example of a ball and socket joint?
Ankle
Shoulder
Knee
Metacarpophalangeal
The Correct Answer is B
A. Ankle is incorrect. The ankle is a hinge joint, which allows for movement in one plane (up and down), not the multidirectional movement characteristic of a ball and socket joint.
B. Shoulder is correct. The shoulder joint is a ball and socket joint. This type of joint allows for movement in multiple directions, including flexion, extension, abduction, adduction, rotation, and circumduction.
C. Knee is incorrect. The knee is a hinge joint, allowing for flexion and extension but not the wide range of motion that a ball and socket joint offers.
D. Metacarpophalangeal is incorrect. The metacarpophalangeal joints (knuckles) are condyloid joints, which allow for movement in two planes but not the full rotational movement of a ball and socket joint.

Correct Answer is C
Explanation
A. Documenting in the nursing care plan is incorrect. The nursing care plan outlines interventions and client needs, but it is not used for documenting medication errors.
B. Recording in the controlled substance inventory record is incorrect. While the administration of a controlled substance must be recorded, the inventory record tracks medication usage and does not serve as documentation for errors.
C. Completing an incident report is correct. An incident report is used to document medication errors, allowing for review and quality improvement measures to prevent future occurrences.
D. Writing in the provider's progress notes is incorrect. The provider's progress notes focus on client status and treatment plans, not internal error reporting. However, the nurse should notify the provider about the error.
Correct Answer is C
Explanation
A. "Assign the task to another AP" is not the best first response. The nurse should first understand why the AP is refusing the task and address any concerns before reassigning the task.
B. "Report the AP to the risk manager" is premature. The nurse should first attempt to understand the AP’s reasons for refusal and resolve any concerns directly. Reporting should only occur if the issue persists and cannot be resolved.
C. "Discuss the AP's concerns about performing the task" is correct. The nurse should open a dialogue with the AP to understand why they are refusing the task. This allows the nurse to assess if the refusal is due to lack of knowledge, skill, or comfort, and then provide the necessary support, guidance, or training.
D. "Perform the task on behalf of the AP" is not ideal. The nurse should not assume the task but rather address the issue with the AP. The nurse should only intervene if the task needs to be completed urgently, but the first step should be to explore the reasons for refusal.
